The value of t for a t-distribution with 15 degrees of freedom is -2.131.

A Z-score is a metric that quantifies how closely a value relates to the mean of a set of values.

Standard deviations from the mean are used to measure Z-score. A Z-score of zero means the data point's score is the same as the mean score.

Given:

Degree of freedom df = 15

and area to the left of t = 0.025

Hence, area right of t = 1-0.025 = 0.975

From the table of t-distribution for the area left of t = 0.025 and 15 degrees of freedom, the corresponding value of t is -2.131.

Step-by-step explanation:

The speed and the direction of the resulting blob of clay is 1.4m/s and 57.46 deg below +ve x-axis respectively.

The Latin word for carrier is vector. Points A and B are transported by vectors. The magnitude of the vector is the length of the line connecting points A and B, and the vector's direction is the direction in which point A moves in relation to point B. Other names for vectors are Euclidean vectors and spatial vectors. In many different domains, including mathematics, physics, engineering, and others, vectors are used.

Since there is no external force applied, So using momentum conservation:

Pi = Pf

Since the wreckage is locked onto each other after collision, So their final velocity will be same

m1*v1 + m2*v2 + m3*v3 = (m1 + m2 + m3)*V

m1 = mass of ball1 = 60 g

m2 = mass of ball2 = 20 g

m3 = mass of ball3 = 30 g

v1 = initial velocity of m1 = 4.0 m/sec towards 45 deg South of east = (4*cos(45deg) i - 4*sin(45 deg) j) m/sec

v2 = initial velocity of m2 = 2.0 m/sec towards North = (2.0 j) m/sec

v3 = initial velocity of m3 = 2.9 m/sec towards west = (-2.9 i) m/sec

V = final velocity of blob = x i + y j

So,

60*(4*cos(45deg) i - 4*sin(45 deg) j) + 20*(2.0 j) + 30*(-2.9 i) = (60+20+30)*(x i + y j)

(60*2.83 - 30*2.9) i + (-60*2.83 + 20*2.0) j = 110x i + 110 j

82.8 i - 129.8 j = 110x i + 110y j

By comparing both sides:

x = 82.8/110 = 0.753 i

y = -129.8/110 = -1.18 j

then, final speed will be:

V = 0.753 i - 1.18 j

Part - A

Speed of resulting blob of clay,

|V| = √((0.753)² + (1.18)²)

|V| = 1.4 m/s

Part-B

Direction after collision will be:

Direction = arctan (Vy/Vx) = arctan (-1.18/0.753) = -57.46 deg

Direction = 57.46 deg below +ve x-axis

Hence, the speed and the direction of the resulting blob of clay is 1.4m/s and 57.46 deg below +ve x-axis respectively.

Answer:

x = 2

Step-by-step explanation:

To obtain a 40% antifreeze solution, we need to add more antifreeze to the 30% solution. Let's call the amount of pure antifreeze that needs to be added x. Then, the amount of antifreeze in the solution will be 2 + x quarts.

The concentration of antifreeze in the solution will be:

(0.30 * 2) + (0.100 * x) = 0.40 * (2 + x)

Solving for x:

0.60 + 0.100x = 0.40 * (2 + x)

Expanding the right-hand side:

0.60 + 0.100x = 0.80 + 0.40x

Solving for x:

0.100x = 0.20

x = 2

So, 2 quarts of pure antifreeze must be added to obtain a 40% antifreeze solution.

Answer: Given f(x) = -4x + 9 and g(x) = x^2 - x - 10, the composition of functions fog(x) is defined as fog(x) = f(g(x)).

To find the value of fog(5), we need to evaluate g(5) first:

g(5) = 5^2 - 5 - 10 = 20

Now that we have g(5) = 20, we can substitute it into f(x) to find fog(5):

fog(5) = f(g(5)) = f(20) = -4 * 20 + 9 = -79

So, the value of fog(5) is -79.

The length of the line segment after the dilation with a scale factor of 2 is given by the equation A' = L ( 2 ) , where L is the length of the segment

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

Given data ,

Let the length of the line segment be represented as L

Now , the dilation factor is represented as d = 2

And , the dilation centered at the origin

So , the length of the line segment after the dilation is A'

On simplifying the equation , we get

The length of the line segment after the dilation A' = L x ( dilation factor )

The length of the line segment after the dilation A' = L ( 2 )

Answer:

  (x, y) = (-4, 3)

Step-by-step explanation:

You want the solution to the matrix equation ...

  [tex]\left[\begin{array}{cc}2&5\\1&3\end{array}\right] \left[\begin{array}{c}x\\y\end{array}\right] =\left[\begin{array}{c}7\\5\end{array}\right][/tex]

Perhaps the easiest solution is to let a calculator reduce the augmented matrix to row-echelon form. This is done in the attachment. It shows the solution is (x, y) = (-4, 3).

Alternatively, you can left-multiply the equation by the inverse of the coefficient matrix. The inverse of the 2×2 coefficient matrix is easily found.

The inverse is the transpose of the cofactor matrix, divided by the determinant. For a 2×2 matrix, the transpose of the cofactor matrix negates the off-diagonal terms and swaps the diagonal terms. The determinant is the difference of the products of the diagonal and off-diagonal terms:

  [tex]\left[\begin{array}{cc}2&5\\1&3\end{array}\right]^{-1}=\dfrac{1}{2\cdot3-1\cdot5}\left[\begin{array}{cc}3&-5\\-1&2\end{array}\right] =\left[\begin{array}{cc}3&-5\\-1&2\end{array}\right][/tex]

Multiplying this by the constant vector, we have ...

  x = 3(7) -5(5) = -4

  y = -1(7) +2(5) = 3

Additional comment

Using row-reduction avoids the problem of the inverse matrix being undefined — when the determinant is zero. That happens when the equations are dependent or inconsistent. The result of row-reduction will tell you which of those is the case: the bottom row is 0 for dependent equations, and 0 0 1 for inconsistent equations.

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

Now according to the given question,

Let cost per kg of clay be x and cost per kg of wood be y.

Then according to the given information in  table, we can get two equations,

5x + 4y = 35.50                                   .....(1)

3.5x + 6y = 50.45                               .....(2)

Now multiply equation (1) by 3 and equation (2) by 2, we get,

15x + 12y = 106.50                               ......(3)

7x + 12y = 100.90                                 ......(4)

Now subtract equation (4) by equation (3), we get,

8x = 5.60

x = 0.7

Now put this value of x in (1),

we get,

5(0.7) + 4y = 35.5

3.5 + 4y = 35.5

subtracting both sides by 3.5, we get

4y = 32

by dividing both sides by 4, we have

y = 8

It is possible that the standard deviation is greater than the mean for a list of positive numbers.

What is standard deviation?

The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability.

Take into consideration, the list of numbers -

1,2,3,4,5,20

The mean formula is - Number of observations / Total observations.

Substitute the values in the equation -

Mean = 1 + 2 + 3 + 4 + 5 + 20 / 6

Mean = 35 / 6

Mean (x') = 5.833

The number of observations is n = 6

The variance is the sum of squared deviations from the mean divided by

n−1.

The standard deviation is the square root of the variance -

s = {√(1 - 35/6)² + .... + (20 - 35/6)²} / (6-1)

s = 7.0828

Therefore, the standard deviation is higher than the mean.

According to the previous sentence, simple interest is equivalent to $157.92.

With only the starting principal and a fixed interest rate, simple yearly interest of government debt interest is calculated. Compounding, which results in borrowers paying tax on both the principal and interest across a number of payment intervals, is not included. To calculate simple interest, multiply the original by the timeframe, rates of return, and duration.

Due to it,

P = $582.09

R = 8.3%

T = 89 days

Now, Simple Interest = P*R*T/100
